>> yes, senator. excuse me. first, i would note that it is french law that they must build a perimeter repository and we might take solace that they had as little luck as we have. they still look to do it in clay repository in the north but have yet to make any progress. they perhaps will continue to extend the loss so they can keep it there while they're doing it but at the end of the day it should be clear that in any regime, whether it's in france, japan, or the united states, we ultimately do need a repository. and while that repository does not need to be yucca mountain, and it may very well have been -- may be a poor choice to follow right now, it remains to be seen on what the future holds. as far as your initial -- your question about cost, about two years ago, before they came in and said they could build a 2,000 metric ton through-put on the order of 15 to $20 billion.
